Abstract

Comprehensive object understanding is a central challenge in visual recognition, yet most advances with deep neural networks reason about each aspect in isolation. In this work, we present a unified framework to tackle this broader object understanding problem. We formalize a refinement module that recursively develops understanding across space and semantics-'the more it looks, the more it sees.' More concretely, we cluster the objects within each semantic category into fine-grained subcategories; our recursive model extracts features for each region of interest, recursively predicts the location and the content of the region, and selectively chooses a small subset of the regions to process in the next step. Our model can quickly determine if an object is present, followed by its class ('Is this a person?'), and finally report finegrained predictions ('Is this person standing?'). Our experiments demonstrate the advantages of joint reasoning about spatial layout and fine-grained semantics. On the PASCAL VOC dataset, our proposed model simultaneously achieves strong performance on instance segmentation, part segmentation and keypoint detection in a single efficient pipeline that does not require explicit training for each task. One of the reasons for our strong performance is the ability to naturally leverage highly-engineered architectures, such as Faster-RCNN, within our pipeline.
